This invention relates to improvements in car construction.

One object of the invention is to provide a combined locking and center pin for railway 5 car bolsters, especially designed for use in' connection between the truck and body 1301-,

sters under all conditions.

Another object of the invention is to pro vide a locking pin having a fixed head at one end and a detachable head at the other end,

together with means for preventing detachment of the last named head.

A still further object of the invention is to provide a locking pin of the character inclicated, having a fixed head at one end and a detachable nut member at the other end, wherein means is provided for locking the nut to the pin against rotation.

Other and further objects of the invention will more clearly appear from the descriptionand claims hereinafter following.

In the drawing, forming a part of'this specification, Figure 1 is a vertical, longitudinal sectional view through the body and truck so bolsters of arailway car, illustrating my'improvements in connection therewith. Figure is a top plan'view of my improved locking pin and Figure 3 is a bottom plan view of the same. And Figure 4 is a transverse, vertical sectional view, corresponding substantially to the line l-d of Figure 1.

In said drawing, 10 indicates a portion of 1 the body bolster of a railway car and 11 a portion of the truck boltser thereof. The truck bolster is provided with the usual center bearing plate 13, having a seat 14 in the top thereof, receiving a cooperating depending bearing section 15 of the body bolster. As shown,

the truck bolster bearing plate 13v is also pro vided with an upstanding central boss 16 which engages within a pocket 17 at the bottom of thebody bolster. The truck and body bolsters are providedwith the usual aligned center pin receiving openings 1818'and each bolster is provided with a head receiving 1928. Serial No. 292,892.

pocket 19 to accommodate one of the heads the center pin. 1

My improved combined locking and center pin comprises a locking pin member proper A, a detachable screw-threaded cap B, and a securing member C.

My improved locking pin member A has the shank thereof of circular cross section so as to fit within the circular pin receiving openings 18 of the body and truck bolsters- As shown, the shank is provided with an integral head member 20 at the bottom end thereof, and has the upper end thereof screw-threaded, as indicated at 22. The head 20 is of such a size as to be accommodated within the pocket 19 of the truck bolster and have shouldered engagement with the top wall of said pocket to prevent removal of the pin in an upward direction. The head 20 of the pin is provided with an eye member 21, with which a tool may be engaged in removing the pin and placing the same in position.

The detachable screw-threaded cap B is in the form of a hollow cylindrical member, having the annular wall thereof interiorly screw-v threaded, as indicated at 23. The cap member B forms, in efiect, a detachable head for the upper end of the pin and fits within the pocket 19 of the body bolster and has shouldered engagement with the bottom wall thereof, to prevent removal: of the pin in a downward direction. The screw cap member B is also provided with an upstanding eye 24, similar to the eye 21 of the head 20, by which thesame may be manipulated. As shown in Figure 4, the eye member has the upper section thereof transversely slotted, as indicated at'25, to accommodate a portion of the securing member C. At the opposite sides, the screw threads 22 of the pin are cut away to provide vertical slots 26-26 which also cooperate with the securing member. The top wall of the detachable screw cap B is also provided with a pair of openings 2727 and the threads of the cap are slotted inalignment therewith, the openings and slots of the cap being adapted to be aligned with-the slots 26 of the pin, to cooperate with the securing member C. Y

The securing member C is in the form of a U-shaped clip, having a horizontal top section 28 and downwardly extending arms 2929. When the screw cap B is secured to the upper end of the pin by engaging the threads of the cap with the threads 22 of the pin, and the slots 26 of the pin have been brought .into

alignment with the openings '27 and the slots' of the cap, the securing men'iber C is at ached by inserting the arms 29 thereoi through the openings 2'? of the cap into the slots of the cap and the slots 26 of the pin and seating the section 28 within the slot 25, the arms 29-29 forming key members cooperating with the slots. As will be evident, the cap B is thus locked to the pin against relative rotation and accidental removal oi the cap is prevented. The arms of the securing memberC are of such a thickness as to snugly fit the openings 2'! of the cap and the slots 26 of the pin, so that when the securing member has been driven home the same will be held in position by frictional contact. The securing memher is preferably made of spring steel and the thereoi are so designed that they will be spread apart slightly when the securing member is detached, whereby the spreading tendency of the same aids in holding thesecuring member in place when applied.

Although in the present instance the lockin g pin has been shown as providedwith the detachable head at the upper end, it is obvious that the same may be soarranged that the detachable head is located at the bottom end thereof. In the present instance, the pin is assembled with the body and truck bolsters by inserting the same through the opening 18 of the truck bolster so that the head 20 will cooperate with the top wall of the pocket 190i said bolster. After the pin proper has thus been placed in position, the screw-threaded cap B is engaged with the upper screwhreaded end oi the pin and locked by the securing member C, as hereinbetore pointer out. lVhen the pin has thus been assembled with the body and truck bolsters, the bolsters are eti'ectively locked against relative sepe-ntion,

thereby preventing telescoping of the cars in case of collision or other accident. As hereinbefore pomted out, the locking pin may be inserted from the top through the body bolster in certain instances, the detachable screw cap being in that case accommodated within the pocket 19 of the truck bolster.
